使用Nginx反向代理服务器隐藏客户端请求标头
我有一个Nginx websocket反向代理，我想从客户端请求中隐藏一个HTTP标头.
I have a Nginx websocket reverse proxy and I would like to hide a HTTP header from the client request.
proxy_hide_header隐藏服务器响应标头，不能用于隐藏客户端请求标头.
proxy_hide_header hides the server response headers and can't be used for hiding client request headers.
我想这样做是因为nginx后面的websocket服务器不能与websocket扩展名"permessage-deflate"配合使用，因此我想从客户端请求中删除Sec-WebSocket-Extensions标头.
I would like to do that because the websocket server behind nginx doesn't work well with the websocket extension "permessage-deflate" so I would like to remove the Sec-WebSocket-Extensions header from client requests.
您可以将标头值设置为void，Nginx会将其删除:
You can set a header value to void and Nginx will drop it :
proxy_set_header Sec-WebSocket-Extensions "";
